In suspension bridges, flutter is the primary source of instability, commonly controlled by a tuned mass damper (TMD). In torsional motions, such as flutter, the shape of the mass block, indicating its distribution around the torsion axis, is critical; indeed, an optimal distribution results in a more effective and lighter device. The flutter analy...
